Publication number: 20250123101Abstract: The present disclosure provides a device and a method for measuring levelness of a top cover of a reactor pressure vessel. The device includes a mounting and fixing mechanism, an inclination sensor mounting base, and an inclination sensor. The mounting and fixing mechanism includes a mounting bottom plate, and a fixing mechanism disposed on the mounting bottom plate. The inclination sensor mounting base includes a bearing plate located on the mounting bottom plate, and a portal frame disposed on the bearing plate and having a top surface. The inclination sensor is mounted on a sensor mounting surface of the bearing plate and located in the portal frame, and configured to obtain levelness of the sealing surface of the top cover by measuring levelness of the sensor mounting surface of the bearing plate.Type: ApplicationFiled: December 19, 2024Publication date: April 17, 2025Inventors: Wenfa WANG, Heng PAN, Zhuangzhuang DONG, Pengfei ZHANG, Bin LIN, Ming LIU, Zhengdi YANG, Heng GAO, Tao LIU, Yongkang SHUAI

Patent number: 12252942Abstract: A rolling and sliding adaptive device for guiding and fixing a drill pipe includes a mounting platform, where the mounting platform is provided with a through hole for the drill pipe to pass through. Multiple rolling and sliding support mechanisms are arranged around the through hole. The rolling and sliding support mechanisms each include a support seat. The support seat is provided with a contact element telescopic and swingable on the support seat. A telescopic drive mechanism is provided between the contact element and the support seat. The contact elements on the multiple rolling and sliding support mechanisms form a funnel-shaped structure with a large upper part and a small lower part around the through hole. The rolling and sliding adaptive device is used on a deep in-situ high-fidelity coring calibration platform for accurate positioning of an assembly process of a multi-section drill pipe bin.Type: GrantFiled: September 23, 2022Date of Patent: March 18, 2025Assignee: SICHUAN UNIVERSITYInventors: Zetian Zhang, Heping Xie, Ru Zhang, Ling Chen, Yihang Li, Heng Gao, Jianan Li, Wei Huang, Li Ren, Kun Xiao, Weiqiang Ling, Chendi Lou

Patent number: 12071820Abstract: A high-temperature and high-pressure simulator for a deep in-situ environment is provided. The simulator includes a high-fidelity sample chamber, where a lower end of the high-fidelity sample chamber is provided with a bottom cylinder. A lower end of the bottom cylinder is provided on a base. A piston rod of the bottom cylinder extends into the high-fidelity sample chamber, and an upper end of the piston rod is provided with a rock sample seat. An upper end of the high-fidelity sample chamber is provided with a rock sample cap. The top of the high-fidelity sample chamber is sealed by an end cap of the high-fidelity sample chamber. An upper end of the end cap of the high-fidelity sample chamber is provided with a multi-section coring drill chamber. The uppermost section of the coring drill chamber is connected to a lift cylinder.Type: GrantFiled: August 22, 2022Date of Patent: August 27, 2024Assignee: SICHUAN UNIVERSITYInventors: Ru Zhang, Heping Xie, Zetian Zhang, Li Ren, Zhilong Zhang, Yihang Li, Weiqiang Ling, Heng Gao
